摘要(Abstract)：

提出沉积韵律控制下的厚层砂体水淹级别精细划分方法.该方法以稳定泥岩隔层为划分标志,将测井曲线划分为与沉积韵律一一对应的解释单元.根据深(浅)电阻率曲线与密度测井曲线,以厚层砂体电阻率曲线的平均斜率及密度曲线的相对重心为判别参数,利用计算机自动判别每一个解释单元中所包含的原始沉积韵律类型.以每单一韵律中部为对比标准层,将韵律其他部位小层的电性、物性、时频特征参数与之比较,结合小层与标准层相对位置关系,自动判定各小层水淹级别.11口密闭取心井处理结果表明:该方法可以有效给出不同韵律内部各小层的水淹级别,与岩心分析结果相比,总符合率达到78%以上.

关键词(KeyWords)：水淹级别;解释单元;沉积韵律;标准层;泥岩夹层;厚层砂体
